I've read through this topic. I've gotten...basically a rant via Discord. I must say I agree here, sorry Ana. She's also concentrating on the times Felix is a jerkass, and choosing to hate him because he gets more love in the fandom than Sylvain. She hasn't said this explictly but I can see that's what's going on here. Meanwhile I'm over here liking both Felix and Sylvain. I can like both. Both have their good and bad. Both shine more when shipped, perhaps. I know Felix when paired with Annette is pretty darn good, basically salt and sugar.
All of the lions, and most of the cast of 3H in general, are good characters that I can like to a certain degree.
